International Comfort Products C9MPD100J14C1 Defrost Sensor Board
The defrost sensor control board is jobbed with determining when to begin the defrost sequence which may be necessary to get rid of the frost that collects on the outdoor unit. The control board relies on a sensor which is near the condenser somewhere, in order to decide when to initiate the defrosting cycle.
Key symptoms of a defective defrost board
- Unit defrost session does not run especially when there is frost that needs to be removed
- The main board might give out a specific error code if the defrost control board fails
- Air conditioning may stop working for the simple fact of the frost blocking the flow of air
